Abstract
A projectile includes: (a) a cured, toughened polymer resin; and (b) a particulate filler distributed through the resin, the filler having a density greater than a density of the resin, wherein the projectile has average density less than the density of lead.

A projectile comprising:
- (a) a toughened polymer resin comprising an elastomer-modified epoxy functional adduct formed by the reaction of a bisphenol A liquid epoxy resin and a carboxyl terminated butadiene-acrylonitrile elastomer;
- (b) a particulate filler distributed through the resin, the filler having a density greater than a density of the resin;
- and
- (c) a curative agent by which the toughened polymer resin with distributed particulate filler is cured;
- (d) wherein the projectile has an average density less than the density of lead.
